: Hi Tim,
: I read one of your responses concerning engine ticking further down the board.I just got my A back on the road Sunday with a rebuilt engine only to find a peculiar rapping coming from the fan area of the water pump.I ran the car briefly without the fan belt and the sound wasn't there.I'm assuming that it's a spent roller bearing.I have a new cast aluminum fan that has been balanced and the water pump is just rebuilt with a stainless shaft, teflon nut, etc...I also have a collar on the front of the shaft to control end play in the shaft.I installed the pump and lubed it properly, and now I have this rapping.
: You had stated that you had a faulty bearing from the get go.Could you please elaborate on what exactly you found during disassembly. (Broken needles, scored shaft...) and could you please tell me what components you ended up replacing. (Bearing sleeve, cup washers etc...) This would be of a tremendous help to me.
: Thank You,
: Kevin Daly
: PSWhen I took off the fan belt, I spun the pump by propping the fan and heard no rapping at all.The rapping seems to happen more at idle than any other time, however it rears it's ugly head at any time.
kevin,
A couple of guys in our club ran into a few unusual problems recently with the aluminum fans. On one the inside of fan hub has so out of round it made you dizzy to look at it, fortunately it just looked bad...didn't make any noise.The other one had a defective taper in the hub, that one did make noise.I don't know if that could be your problem, but I figured you might be interested.
